Bear Hazard Assessment Report Port Alberni, British Columbia Bear Smart Community Program, Phase I November 2007 Prepared for City of Port Alberni 4850 Argyle Street Port Alberni BC V9Y 1V8 Phone: 250-720-2810 [email protected] Prepared by Maggie M. Paquet 5232A Margaret Street Port Alberni, BC V9Y 6J2 Phone: 250-723-8802 [email protected] Acknowledgements The writer received input and assistance from District Conservation Officer Ben York and CO Mike Stern, particularly with respect to obtaining data on bear-people conflicts in and surrounding the City of Port Alberni. Thanks to Ben and Mike, too, for their support in making presentations to the Port Alberni City Council on the status of bear-people conflicts in the city. The writer also thanks Port Alberni Mayor and City Councillors for approving the application to the Conservation Officer Service, Bear Smart Community Program for the funding for this report. City Clerk Russell Dyson was most helpful in the administration of this project. Cara Foden, Planning Technician in the Planning Department, was generous with her time and expertise in providing me with city maps; I am grateful for her heroic efforts to produce the bear-sightings maps contained in this report. Other city staff and school district employees also contributed to the report. Many thanks go to Greg Freethy at ADSS, and two student assistants, Kristy Aikman and Marinka Kurucz, for helping me map the bear-people conflict reports. I would also like to thank a handful of Port Alberni residents who freely contributed their stories about their experiences with bears (even when some of those calls came in the middle of the night!). I’d also like to thank Bear Smart Communities Coordinator Mike Badry of the BC Ministry of Environment, Wildlife Branch, who provided information and advice. I would like to acknowledge the expertise and advice contained in the report: “Bear Smart” Community Program: Background Report, by Helen Davis, Debbie Wellwood, and Lana Ciarniello; and in the report Hazard Assessment of Bear-Human Conflict in Stewart, British Columbia—Phase 1, by Debbie Wellwood, RPBio, Raven Ecological Services, Smithers, BC. As well, the MSc Thesis of Helen Davis, Characteristics and Selection of Winter Dens by Black Bears in Coastal British Columbia, 1996, also informed this report. Ms. Davis’ thesis offered considerable insight into the behaviours and habitat requirements of black bears on Vancouver Island, which are a subspecies of North American black bears distinct from the subspecies found on mainland BC. Bear biologist Wayne McCrory (RPBio), of McCrory Wildlife Services, New Denver, BC, continues to mentor my work in this field. For his advice, assistance, and moral support, I am truly grateful. Sean Sharpe, RPBio, of the BC Environment Ministry, Prince George, also continues to review my work and offer advice and support, for which I thank him from the bottom of my heart.
